Almost half of the top 20 software titles at U.S. console retail in November 2009 were for Nintendo systems, according to results released by the market tracking NPD Group, including six published by the platform holder itself.

The top 10 list released yesterday already revealed Activision Blizzard's Call of Duty: Modern Warfare 2 had dominated sales for the month, with total Xbox 360 and PlayStation 3 sales of over 6 million units.

Wii Play, the minigame collection originally released in February 2007, placed 11th on the extended list and Sega's Mario & Sonic at the Winter Olympic Games ranked 12th. For the DS, Nintendo's own Mario & Luigi: Bowser's Inside Story remained at 14th for the second month in a row.

In addition to these name-brand packages, a generic software bundle for the Nintendo Wii and another for the DS, each denoted Value Game Bundle by the NPD Group, appeared on the chart at positions 13 and 16, respectively.

Presumably these are pairs of discounted third-party titles shrinkwrapped together for convenient sale. According to the listing, the Wii version was priced at $19.99 and the Nintendo DS version at $14.99.

Microsoft's Xbox 360 had three additional titles at the end of the listing. Its own Halo 3: ODST made another appearance as the 18th best-selling game, dropping from 6th on last month's chart. The Xbox 360 version of Borderlands from Take-Two Interactive dropped from 3rd to 19th and the Xbox 360 version of Madden NFL 10 from Electronic Arts dropped from 18th to the bottom of the chart.

The PlayStation 3 version of Dragon Age: Origins, published by Electronic Arts, debuted at number 15, several spots below its Xbox 360 counterpart. The God of War I & II Collection, a PS3 remake of the classic PlayStation 2 titles, was 17th for the month.

Given that God of War III is a flagship title for Sony's console in the first quarter of 2010, the remake reaching the top 20 may be a positive sign ahead of the game's launch.

The full Top 20, as provided to Gamasutra, is as follows:

According to comments by Michael Pachter of Wedbush Securities, 34 titles sold over 100,000 units in November 2009. As a result, each title in the latter half of the top 20 must have sales between 315,000 units and 100,000 units.
